I had some Cochin bantam eggs that are due to hatch soon. I noticed an egg piping and kept a close eye in it. I just went outside to notice blood on other eggs and the piping egg had blood around the pip and a tiny bloody wing sticking out. Thinking it was dead as it wasn’t moving or peeping I took it out and opened the egg to see an underdeveloped chick and a yolk sack still attached. The chick was peeping so I put it in a bowl on a towel with the egg still attached in the incubator. I don’t know what to do and hoped someone would have some advice.
